Answer:
150
Step-by-step explanation:
Right now the dirt bike is worth $500. Next year it will be worth 15% less, or 85% of the current value (because currently it's at 100%, so you would subtract the 15%). To find 85% of the dirt bike's value, you would take $500 and multiply by 85% (or 0.85). This would give you $425 after 1 year. You'd take $425 and multiply that by 85% for the next year, and continue until you reached 5 years of the value decreasing. Does this help?
Answer:

Step-by-step explanation:
Given
and 
Required
Determine the coordinate of the midpoint (M)
This is calculated as thus:

Where
-- 
-- 
So, we have:




Hence, the coordinates of the midpoint is (2,2)
77x + 21
We need to find the common factor between the coefficient and the constant.
77 ÷ 7 = 11
21 ÷ 7 = 3
7(11x + 3) is the factor of 77x + 21.
7(11x + 3) can be expanded using the distributive property of multiplication.
7(11x) + 7(3) = 77x + 21
If <5=42 you multiply 5 by 8.4=42
so m <4 is going to be 33.6
4X8.4=33.6
